Semmy [17]

Answer:

The correct answer is D) domain

Explanation:

The father of taxonomy is Linnaeus. Taxonomy helps in classify and naming organisms. The modern taxonomy has eight levels of classification. Domain, kingdom, phylum, class, order, family, genus, species.

Domain is the highest level of classification so it is the largest category that would include closely related species.

You are given a 1 liter bacterial culture in exponential stage of growth. The generation time of the bacteria is known to be 30
nydimaria [60]

Answer:

Option-A

Explanation:

A bacteria divides by binary fission which divides a parent bacteria into the two daughter cells and generation time refers to the average time difference between two consecutive generations.

The bacterial cell grows by the exponential function that is by 2^{number of generation} x initial population of bacteria.

In the given question,

<u>Initial population</u>

the initial population of bacteria - 2x 10³ per ml

So per liter, the bacterial population will be 2 x 10 ⁶

<u>Generation time</u>

1 generation time of bacteria is 30 min.

so 5 hours will have- <u> </u>\frac{300}{30}= 10 generations

<u>New bacterial population</u>

Using formula<u>  </u>2^{number of generation} x initial population of bacteria

2^{10} x (2 x 10⁶)

= 1048 x (2 x 10⁶)

2048 x 10⁶

Thus, Option-A is the correct answer.

Some scientists claim that humans are responsible for the increase of CO2 in the atmosphere. Evaluate which system the increased
forsale [732]

Yes, human activities are a significant cause of the increase in the amount of Carbon dioxide in the atmosphere.

<h3><u>Explanation:</u></h3>

The increasing amount of CO_2 is a big problem in today's world for the atmosphere. Human activities are playing a vital role in the rise in CO_2. Carbon emission is majorly happening because of pollution. The pollution by vehicle, wax factories, chemical factories, etc. also, some other kinds of Carbon emission activities are there like burning coal and plastic produces Carbon in very high amount and this Carbon directly mix into the atmosphere.

Due to the increase in CO_2, both natural and agricultural ecosystems are suffering. CO_2 causes air pollution, and because of that, the quality of crops is declining day by day. Also, the natural vegetation is struggling as the rainwater is also not pure; the amount of acidic content in natural rain is increasing per year. All these activities are leading towards global warming, which one day will bring our earth to an end. So it is imperative to take some severe legal measures to save the environment and decline the amount of CO_2 producing.
